Ultrasonic open channel flowmetersasetshenziswa eziteshini zokuphambukisa ukuphakelwa kwamanzi emadolobheni, isizinda sokupholisa amanzi sokuphambukisa kanye nemigudu yokukhipha indle, imigudu yokungena nokukhipha indle yokuhlanza indle, uketshezi lwamakhemikhali, nokuchithwa kwamanzi angcolile ezimbonini nezimayini, kanye namaphrojekthi okonga amanzi kanye nemigudu yokunisela yezolimo.
Ikakhulukazi ukuze wenze le ncazelo elandelayo mayelana nezinyathelo zokuphepha zokufakwa kwe-flowmeter yesiteshi esimenyezelwe kakhulu, khumbula ukuyiqoqa uma uyidinga.
1. Isivinini sokugeleza esilinganisiwe sisekelwe esisekelweni sokuthi iphethini yokugeleza kwesiteshi ithuthukiswe ngokugcwele, okungukuthi, ingxenye eqondile yesiteshi (ipayipi) iyadingeka ukuze kuhlangatshezwane nezidingo.
2. Uma ingxenye eqondile yesayithi inganele, umthelela wokugeleza kwe-diagonal ekunembeni kwesilinganiso sesivinini sokugeleza kufanele unxeshezelwe ngokusetha umzila womsindo kuso sonke isigaba sokulinganisa.
3. Uma kukhona ama-weir, amasango, nezinye izinsiza ngaphambi nangemuva kwesigaba sokulinganisa esikusayithi ukwenza ukugeleza okuqondile kube nesiyaluyalu, indlela yokulinganisa yamashaneli amaningi kufanele isetshenziselwe ukukala ngokunembile isivinini esimaphakathi sobuso. Inani lamashaneli omsindo nokuphakama kwamashaneli omsindo kunqunywa ngokuhambisana nezidingo zokunemba kokulinganisa, futhi izinga elincane lamanzi, izinga eliphezulu lamanzi, kanye nezinga lamanzi asebenzayo nakho kufanele kucatshangelwe.
4. Kumamitha okugeleza kwesiteshi, kubalulekile ukukala ngokunembile izinga lokugeleza kanye nezinga lamanzi, kodwa iphutha lendawo ephambanayo yesiteshi ngokuvamile liyithonya elikhulu esilinganisweni sokugeleza (isibonelo, ukuchithwa kwenhlabathi phansi kwesiteshi. , udonga lwesiteshi olungalingani, nobubanzi beshaneli obungahambisani namanye amaphutha). Ngakho-ke, okuhlongozwe ngokukhethekile lapha ukuthi ukulawulwa kwephutha lendawo ephambanayo yesiteshi kufanele kuqale ngokwakhiwa kwesiteshi.
Okunye ukukhetha kwemitha yokugeleza kwe-ultrasonic:
